Nutritional Highlights – A Healthy Side That Feels Like a Treat
Brussels sprouts are a nutritional powerhouse. They’re loaded with vitamin K, vitamin C, fibre, and antioxidants that support heart health, digestion, and immunity. When you add a moderate amount of olive oil and Parmesan, you get a satisfying, flavourful side dish that’s low in carbs (about 10g per serving) and high in protein (8g from the Parmesan). The fats are mostly heart‑healthy monounsaturated fats from the olive oil.
For a lower‑fat version, you can reduce the oil to 1 tablespoon – the sprouts will be slightly less crispy, but still delicious. If you’re dairy‑free, you can substitute the Parmesan with a plant‑based nutritional yeast or a dairy‑free Parmesan alternative – the texture will be different, but the flavour will still be satisfying.
One serving (about ¼ of the recipe) contains approximately 180 calories, making it a nutrient‑dense, relatively low‑calorie side that you can feel good about enjoying regularly.
Frequently Asked Questions
Can I use frozen Brussels sprouts? It’s best to use fresh for this recipe, as frozen sprouts release too much moisture and won’t crisp up properly. If you must use frozen, thaw and pat them very dry – but fresh will always give better results.
Why are my sprouts not crispy? The most common culprits are excess moisture (pat them dry!), overcrowding the basket, or not using enough oil. Make sure your air fryer is preheated and you’re cooking in a single layer.
Can I make these ahead of time? They’re best fresh, but you can prep the sprouts (trim, halve, and toss with oil) a day ahead and store in the fridge. Air fry just before serving.
What if I don’t have an air fryer? You can roast them in the oven at 425°F for 20–25 minutes, flipping halfway. They won’t be quite as crispy, but still delicious.
Can I add more cheese? Absolutely! If you want an even cheesier crust, you can increase the Parmesan to ¾ cup – just keep an eye on the last few minutes of cooking so the cheese doesn’t burn.
